Nice post! I almost completely agree with your list, with the only exception being the Dhampir Infiltrator.
I think it's going to be more impactful, as its stats are really good and Sneak is very strong in lower mana games. Having Affliction on a Sneak monster also directly counters Triage and because it has Double Strike it should hit the Affliction very easily.
I see where you are coming from but there are popular cards which counter her really easily such as mylor. In fact, she'll take 4 damage after turn 1 due to thorns and that squishiness that even 3 mana cost sneak cards don't have is what made her A tier instead of a higher tier.
